So I tried: probiotics, biotin in high doses, Apple Cider Vinegar internally and topically, coconut oil, tea tree oil, lavender oil, natural yeast treatments and the thing I found to work best is a combination of herbs found in a tincture- Milk Thistle, Yellow Dock. I am now taking milk thistle, yellow dock and burdock root (also in the above tincture) and I am like a new woman! These herbs have been described to me as "blood cleaners" and are all used for liver health. I looked like a dermatology pamphlet and now my skin is nearly flawless. Nothing else worked like this.
